Looks like overwatering and/or improper drainage. Do not soak the soil with every watering, as this will flush the nutrients out of the soil, and cause root-rot. Is there perlite in the soil?
Once yellowing and splotching (leaf die-off) wanes, likely ok to start a weak nutrient solution. Half strength at first, keep an eye on results and adjust accordingly.
